Performance Investigation of Dual Wavelength Fiber Laser using different SOAs

Abstract

We investigated the performance of a dual-wavelength fiber laser using different types of semiconductor optical amplifiers (SOAs) utilizing fiber Bragg gratings (FBGs) as comb filter. The lasing performances of linear SOA (LSOA), nonlinear SOA (NLSOA) and booster optical amplifier (BOA) at different current setting were observed. LSOA produced the flattest spectrum based on its peak power difference at only 4.5 dB as compared to 66.4 dB using BOA. BOA has the worst flatness because its polarization sensitivity is the highest as compared to LSOA and NLSOA. Overall, the best lasing performance is when LSOA is used due to the lowest peak power difference with high peak power at-17.6 dBm.

Investigation of Multiwavelength Performance based on different SOAs

“…Besides that, SOA has a simpler setup than EDFA since it does not require optical pumping. Based on SOA's advantage, there is an increasing number of studies on the generation of multiwavelength SOA fiber lasers with different comb filters [10,[13][14][15].…”

“…Recently, Sulaiman et al demonstrated using a Sagnac loop mirror [SLM] interferometer, producing 164 lasing lines by adjusting the PCs [17]. Other than the studies mentioned earlier, fiber Bragg grating (FBG) [15] and Mach-Zehnder interferometer (MZI) [18] also received significant interest from other researchers. There are also studies on the combination of two comb filters in a system [8,[19][20].…”
